HERMAN I. BU'SCH, OF MILLV'ALE, PENNSYLVANIA, ASSIGNOR TO ARMSTRONG GORK COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

MACHINE FOR-CUTTING snnnrs or CORK PAPER.

To all whom it may concern:

Be it knownt at I, HERMAN F. Boson, a citizen of the United States, residing at Millvale, in' the county-of Allegheny and Stated Pennsylvania, have invented a new and useful Improvement in Machines for Cutting Sheets "of Cork Paper, of which the following is a full, clear, and exact descriptipn, reference-being had to the accompanyin'g drawings forming part-of this specification, in which- Figure l is a plan view of a machine ems bodying my invention; Fig. 2 is an end elevation looking toward" the upper end of Fig. 1; Figs. 3 and 4 are sections taken, respectively, on the line III-III and IVIV of Fig.1; Fig. 5 is a plan view of the rotary carrier or magazine for the cork blocks; and F ig- 6 is a detail perspective view of one of the cork holders.

- Y My invention has relation to machines for cutting sheets of cork paper from cork blocks, and is designed to provide a machine of this character" which is simple and reliable in its' 0 eration, and by means of which the wor can be veryrapidly done. Alsov to lprovide a machine of thls character bywhic sheets of any desired thinness, up to about four hundred sheets per inch, can be accurately cut.

The nature of my'invention will be best understood by reference to the accompanying drawings, in which I have shownone embodiment thereof and which will now be described, it being premised, however, that various changes may be made in the maright angles to chine, without departing from the spirit and scope of my invention, as defined in the appended claims.

In the, drawings, thenumeral 2 designates the supporting frame of the machine, which is formed'at its top portion with suitable guides 3, to receive a'longitudin'ally-movable table or slide 4. 5 ma second slide or table which is mounted on] suitable guides 6, of the slide or table 4, to inove thereon-trans verselyor in a direction. substantially at the directioiiiof movement of the slide'4. a J j 7 designates a suitabldshaft or arbor driven in any suitable mannehfas by'a pulley 8, and having at its overhanging end the disk cutter 9, which rotates in a "vertical". plane.-

' The numeral 10 designatesa"rotary'carrierv Specification of Letters Patent.

' or magazine to the periphery of which are secured the cork blocks to be cut into sheets. Thiscarrier is of generally circular form, and is rigidly secured to a vertical driving shaft 11. The peripheral portion of the car- '60 mar is formed with a plurality of vertically extending V-shaped guideways 12, each adapted to receive a segmental cork holder 13. Each cork holder is formed with the dovetailed. projecting portions. 1d on the inner face thereof, to "slidably engage the ways or guides 12. Each carrier is also referably provided with a suitable hand e 15 at its upper end' to facilitate its insertion into. and removal from the carrier. The opter' convex face of each holder consists of a segment of a cylindrical surface, whose radius is struck from the center of the shaft 11. The cork blocks A which are to be out are suitably secured to these holders, preferably by coating them with a suitable hot cement and pressing them firmly on to the convex surface ofthe holder. When the cement has cooled, the holders are placed in the carrier as required. It will be seen that the cork blanks in being applied to the holders are bent to conform to the curvature of the convex outer sides thereof and when placed in the carrier areso positioned that gential to the'outer surface of the blocks. ,Secured to the shaft 11 below the carrier and also secured to the carrier is alarge gear wheel 16, having an annular double beveled bearing portion 17 on its lower face which is adapted to rotate in the correspondingly shaped raceway or bearing 18 on the upper face of the table 5. In order to relieve this bearing somewhat, the lower end of the shaft llmay be stepped upon an adjustable 95[ bearing screw 19, seated in the table 5. This screw by roperadjustment can be made to take any" 'es'ir'edfpart of the load, a'nd thus relieve 'th' bearing on the annular race- Wa'y'18. a

effected; by a continuous feeding movement imparted tothe' table 5. This may" be effected in any suitable manner, as may also I have shown "the gearing now to be described. J

The large gear wheel 16, which is attached to the carrier, isdriven by a pinion 20, journal ed on the table 5 and whichis driven by 110 the rotary movement of the carrier or magashaft 22 carries a bevel gear wheel 23, which is drivenby a pinion 24, on the transverse shaft 25, carrying the loose pulley 26 and the fast pulley.27.'

28 is a belt shifter for shifting a driving belt from one of these pulleys to the other, to thereby control the operation of the rotary carrier. This belt shifter may be operated by connections, such as indicated at 29 and 29, extending to the operators station.

'30 is a bevel gear wheel on the upper end of the shaft 11', which drives a corresponding geaf'whee'l 31 on the longitudinal shaft 32. This shaft carries a pinion 33 which, through the trainof reducing gears 34, 35, 36, 37, 38 and 39, drives a longitudinal shaft 40, at one'side-of the table 5 and supported in suitable bearings 41, carried thereby. The-shaft 40 may have any desired number of bevel gears 42 (two being shown) each of which drives a bevel gear 43 on transverse shafts 44. The shafts 44 engage nuts on the under side of the table 5.

By the driving connections last described,

zine actuates the shaft 40, and thereby through the shafts 44, imparts a continuous feeding movement of the table 5 and of the carrier toward the cutter 9, to make succeslsli ve cuts. In this feeding movement, it

The traim of reducing gearing above described may contain one or more interchangeable members, whereby the rate of feed can be varied to vary the'thickness of the paper sheets as may be desired.

In order to enable the table to be quickly run up to the cutter or backed away from it,

the gear 39 is connected with the shaft 40 through a suitable clutch 46. This clutch is controlled by the shifting rod 46, which also preferably extends to. a point near the operators station. When this rod is actuated to throw out the clutch 46, the shaft 40 can be actuated by the hand wheel 47, or any other suitable-means, to .thereby quickly move the table 5 toward and away from the cutter.

- The longitudinal movement of the table 4 is for the purpose of adjustingthe table 5, carried thereon, to compensate for wear of the cutter. These cutters wear quite rapidly, and in operation become greatly reduced in diameter before being discarded.

be seen that all-the gearing moves with the table 5, being mounted thereon.'

from the provision of a machine having a rotary magazine or cork carrier to and from which the cork blocks can be readily secured and removed and which holds the said blocks in curved form, so that the cutter can operate thereon' in a tangential plane, said carrier being capable of a continuous feeding movement toward the cutter. In this manner, a very considerable number of cork blocks can, be simultaneously mounted on one carrier capable ofa relatively high s eed of rotation. This enables the mac line to have a large total output, as well as extreme accuracy in operation. The actual use of a considerable number of these machines has demonstrated that each machine is capable of cutting from fifteen thousand to. twenty thousand cork sheets, per day, and that the sheets produced are of uniform and perfect character and can be actually out to a much greater degree of thinness than has heretofore been possible with accurate work.

It will be readily understood that the machine is capable of wide variations in the details. Thus, any suitable gearing may be provided for driving the rotary carrier, as well as for operating the feeding movement of the carrier, and various other changes may bemade.

I claim: s a

"1. A machine of the character described, comprising a rotary support for the cork blocks, means for holding the cork blocks thereon in curved position, a cutter arranged rality of peripheral seats, cork -holders adapted to be removably secured in said seatsand having curved outer surfaces to which the cork blocks to be out are secured, a tangentially arranged cutting disk, and means for imparting a feeding movement to the carrier, substantially as described.

4. A machine of the character described, comprising a transversely-movable support, a. longitudinally movable sub-support, a rotary carrier mounted on the ptransversely movable support and having means for securingtheretoin curved form a plurality of cork blocks, means for impartinga continuous feeding movement to the first named support and earner, and means for adj ust- .tangentially to the outer surfaces of the scribed.

5. A machine ofthe character described, comprising a rotary carrier having means for securing to the periphery thereof a plurality of cork blocks in curved form, a support upon which the table is mounted, means for imparting a continuous feeding movement to the support and carrier, means for throwing the feeding gear out of action, and other means for actuating the support when the feeding gear is thrown out of action, substantially as described.

6. A machine of the character described,

comprising a carrier movable about a fixed center, means for holding a cork block on said carrier in curved form, a cutter disk tangential, to the outer surface of the cork block on the carrier, and means for imparting a relative-feeding movement between the carrier and, the cutter, substantially as described.

In testimony whereof, I have hereunto set my hand. HERMANF. BUSOH.
